INDICATOR FOB QUANTITY STOPS.

Original application filed September 15, 1824, Serial No. 737,801.

' 26, 1925. Serial No. 32,961.

This invention relates to indicators for quantity stops and the like andis especially adapted for use in connection with the quantity stops ofliquid dispensing apparatus of the types commonly used for dispensinggasoline, to indicate in a novel manner the quantity of gasoline forwhich the apparatus is set to deliver.

This application is a division of my pending application Serial No.737,801, filed September 15, 1924.

The object of the invention is to provide a quantity indicator for eachof the quantity stops of the apparatus, each of said indicators beingnormally concealed from the purchaser but movable into display positionwhen the stop is engaged by its cooperating member, whereby thepurchaser may readily determine the quantity which the apparatus is setto deliver.

Other objects and advantages will appear in the following descriptionand in the illustrative embodiment of theinvention in the accompanyingdrawings, in which Fig. 1 is a small scale elevational view of a liquiddispensing apparatus embodying the invention I Fig. 2 is an enlargedelevational view of one of the quantity stops and the quantity indicatorassociated therewith;

Fig. 3 is an enlarged sectional plan view taken on the line 3-3 of Fig.1; and

Fig. 4 is an enlarged fragmentary sectional elevational view of theapparatus, illustrative of the quantity stops, and of the quantityindicators.

The liquid dispensing apparatus, chosen by way of illustrative exampleas a background for this invention, is of the socalled visible measuringtype. It includes a measuring receptacle having a base 11, a cap 12 anda transparent cylindrical wall 13 disposed therebetween and held inplace by tie bolts 14. Suitable quantity indicators 15 are providedadjacent glass 13 to define the levels occupied by various measured unitquantities of liquid in the receptacle. The base 13 is supported on theupper end of ahollow pedestal 16. The lower part of this p destal housesa suitable pump 17,- that illustrated being of the wing piston Dividedand this application filed May type oscillatable manually by a lever 18.A pipe 19 is adapted to connect the inlet of the pump 16 to the supplytank and a pipe 20 connects the outlet of the pump to the re-' ceptacle10. A pipe 21 extends from the supply tank upwardly into the pedestaland terminates with a suitable stufiing box 22.

An adjustable overflow pipe 23 in receptacle.

trolled by a delivery valve 25, adapted to be,

manually opened by a lever, 26. The operator, by oscillating handle 18,operates the pump and forces liquid into receptacle 10. By verticaladjustment of the overflow pipe or gage tube 23, any excess over thequantity desired by the purchaser is drained back to the supply tank,after which valve 25 is opened to deliver the desired measured quantity,by gravity flow, from receptacle 10 Referring to Figs. 3 and 4, theslidable gage tube 23 has fixed thereto a collar 35, to which. isattached handle 36, extending radially outward. Handle 36 normallyextends out of the pedestal 16 through a recess 37 (Fig. 1) formedtherein adjacent a door 38. When this door is opened, handle 36 may beswung outof recess 37 into the door opening 39 and lifted to set thegage tube at any of a number of predetermined levels. For the purpose ofholding the tube at such levels, a plurality of stop fingers 40 areprovided, each of which has'an upper, horizontal, gaging surface 41 uponwhich handle 36 V is adapted torest. These fingers are secured,

piece :5, pivotally connected intermediate its ends at 46 to the stop 40and normally hanging by gravity in the position shown by full lines insaid figure. In this position, the upper portion of member. projectsabove the surface ll of stop finger so, whereby it is located in thepath or handle 36 and will be engaged and moved thereby as the handle ismoved over such surface. In this manner, the indicator is lifted Fromits depending position and swung through an angle of ninety degrees intothe dispiay position illustrated by dotted lines in Fig. 2. Theindicator may carry any appropri ate marking, usually a name l such as 47, indicating the number of gallons which will be discharged from theapparatus when handle 36 is engaged with the stop. The indicator, exceptfor the portion projecting above surface tl, is concealed when in normalposition by a thin plate 4E8 wnich is at tached to the front face offinger 40. This plate 48 may be extended above siiri'ace 41, as shown,to provide a shoulder 49 to arrest the movement of handle 36 as it ismoved over the surface ll. The contour or the side and lower edges ofplate as such as to prevent the handle 36 from being engaged with thestop finger L0 in any other manner than that intended, viz, with thesurface 41.

The invention has been disclosed herein, in an embodiment at presentpreferred for illustrative purposes but the scope of the invention isdefined by the appended claims rather than by the foregoing description.

vVhat I claim is:

1. In a liquid dispensing apparatus, a plurality of quantity stops, amovable member having a part adapted to be selectively engaged with anyof said stops, and quantity indicators one for each stop and movablymounted adjacent thereto, each indicator being normally concealed behindits moved from its normally concealed position into a display position,

2. In a liquid dispensing apparatus, a visible measuring receptacle, agage tub e movable therein to set the apparatus for the discharge ofvarious predetermined quantities, a plurality of qn ai-itity steps, ahandle by means of which saic gage tube may be manually moved and whichis adapted to be engaged with any of said stops, and a quantityindicator mounted adjacent each stop and displayed by the operation orei'igaging the handle with the selected stop. 3. The combination with afixed quan' tity stop and a movable member adapted to be engagedtherewith, of a quantity indicator mounted adjacent the stop formovement relatively thereto and adapted to be engaged by said member andmoved thereby from a normal to a display position as the latter movesinto engagement with said stop, said stop having a part located in frontof said indicator and serving to con ceal the same when in normalposition.

l. in combination, a quantity stop finger having a horizontal gagingsurface and a shoulder, a member adapted to be moved over said surfaceand against said shoulder, and a quantity indicator pivotally connectedto said stop finger and normally held by gravity in depending relationtherewith, said indicator when in normal position having a partextending above said surface and in the path of said member as it ismoved over said surface, whereby said indicator may be lifted from saidnormal position as said member is moved into position on the stopfinger.
